On average, Jupiter is 779 million kilometers from the Sun, or 5.2 astronomical units (1 astronomical unit, or AU, is the distance from the Earth to the Sun).
I say on average, because Jupiter follows an elliptical orbit around the Sun. When Jupiter reaches its closest point to the Sun, astronomers call this perihelion; this is 741 million km, or 4.95 AU.
And then Jupiter can get as distant as 817 million km (or 5.46 AU) from the Sun; astronomers call this aphelion.
It takes Jupiter almost 4,332 days, or 11.86 Earth years to complete a full orbit around the Sun.
If you're interested, here's an article from Universe Today about how far Jupiter is from Earth.
Windows on the Universe has some interesting statistics about Jupiter. And you can always use NASA's Solar System simulator to see exactly where Jupiter is right now. LINK: http://www.universetoday.com
